Show HN: Record a screencast to practice for your system design interviews

This tool is the culmination of many things in my interviewing experience.

   1. I bought all of system design content; still don't know if I can produce high quality designs
   2. I bought paid interviewing.io SD interview. After it ended, I realized I would've learned just as much by practicing in front of a mirror
   3. I've been tasked with administering many technical phone screens at work and wished it was async
   4. I wish I could prepare for interviews with other people without the scheduling tag game
   5. I realized the interview is more of a performance where you show off how well you can think and talk at the same time.

The recorded video is not uploaded anywhere and there are probably a few bugs

off chance if people want to use this to prepare for their interviews together asynchronously, leave your e-mail here: https://forms.gle/qcJtj97VA1zGZZJ6A
